Hanger shock absorber (hanging ball valve shock absorber) is mainly made of metal ball valve, combined with certain damping materials, and has the functions of low frequency, large damping, wide application range, and obvious vibration isolation and noise reduction effect. The hanger damper is a vibration isolation and noise reduction element combined with a steel ball valve and a series connection, which is suitable for vibration reduction of various pipes and fan coil units, fresh air units, variable air volume air conditioning boxes, axial flow fans, etc. The hanger shock absorber is easy to install, and the lateral damping block is used to increase the vertical damping coefficient, improve the longitudinal and transverse rigidity, and ensure the normal and safe operation of the equipment.
Dongfeng Shock Absorber Factory is mainly engaged in the development and production of suspended ball valve shock absorber (pneumatic butterfly valve), pipeline shock absorber (pneumatic butterfly valve) and new type of damping shock absorber. It is a professional manufacturer of pneumatic butterfly valves in China. Its products are widely used in various pipelines and equipment in industries such as steel, power generation, petrochemical, sludge steel and urban heating, It has been applied to key projects in 31 provinces, cities and autonomous regions across the country. Its performance has spread all over the country and is trusted by users
Firstly, the ball valve shall meet the following requirements: the radius of the ball valve shall be four times greater than the zero point of its height under the rated load; The ball valve shall have a certain additional stroke, at least equal to 50% of the rated static deflection; The number of ball valve coils shall not be too small, generally not less than six; The ball valve manufactured in this way can ensure that the horizontal rigidity of the shock absorber is enough so that the equipment is stable and not prone to toppling, the elasticity is durable, and the lasting shock absorption capacity is guaranteed. However, the price of the ball valve shock absorber is often higher.
According to the weight of the water pump, the reasonable model selection is made. Generally, the compression capacity of the ball valve after the weight of the pressure bearing water pump of the ball valve damper should be more than 20 mm, not more than the rated compression capacity of the pneumatic butterfly valve, so as to ensure the best vibration isolation effect of the vibration damper.
